I did it the other way - beat it on the dark path, now playing through on the light. I'm already finding that more quests open up on the light side (mainly because you actually help people instead of robbing/killing 'em :D ), and light-side powers can be more handy (albeit less fun), such as Destroy Droid and Heal.

I just finished KotOR, very good overall, impressive in almost every aspect. Now I'm playing through it again, but I'm going to go the dark side path this time, much more fun I think, cooler conversations, get to kill innocent people, use Life Drain and stuff, it's going to be good.
